IRON FENCE.

SPECIFICATION forming part of Letters Patent No. 617,993, dated January1'7, 1899.

Application filed June 6, 1898. Serial No. 682,654. (No model.)

T @ZZ whom t may concern:

Be it known that I, JOSEPH F. PLOEGER, of Pittsburg, in the county ofAllegheny and State of Pennsylvania, have invented a new and usefulImprovement in Metallic Fencing, of which the followingisfa full, clear,and exact description, reference being had to the accompanying drawings,forming part of this specification, in which- Figure l is a frontelevation, partly broken away, showing a portion of metallic fencingconstructed in accordance with my invention. Fig. 2 is a verticaltransverse section with the upper locking-plate removed; and Fig. 3 is abottom plan view, partly in section.

My invention relates to that class of metallic fencing where the picketsextend through suitable holes therefor in the upper and lower rails, andis designed to provide a simple and effective construction whereby thepickets may be locked in their position in the rails.

In the drawings, 2 2 represent the upper and lower rails of the fence,these being ordinarily formed of rolled channel sections, as shown,though any suitable shape may be employed. The webs of these channelsare provided with registering holes spaced the desired distance apart,these holes being made of the same shape and size as the pickets 3. Ihave shown the pickets as of square cross-section, set with theircorners toward each other and the holes corresponding thereto; but thepickets and holes may be of circular, triangular, or any other desiredshape. To lock these pickets in place, I notch them on adjacent sidesand preferably at such points in their length as will lie between theflanges of the channels when the pickets are put in place, and intothese notches or recesses I slip the ends of lock-plates 4, which arethen secured to the rails by rivets 5, eX- tending through registeringholes in the channels and the lock-plates. As shown in Figs. l and 3,the lock-plates need only be employed between each alternate pair ofpickets, each of these pairs having the notches or recesses upon theiradjacent sides.

The advantages of my invention will be apparent to those skilled in theart, since a simple, cheap, and effective lock is provided for thepickets and which may be hidden from View and will not interfere withthe painting of the fence.

The lock-plates may be placed upon the upper instead of the Aunder sideof the rail, if desired, the shape of the rails and the pickets may bechanged, and many other varia tions may be made without departing frommy invention, since l. In metallic fencing, a rail, a picket ar# rangedto extend through a hole in the rail, and a lock-plate arranged to besecured to one of these elements and enter a notch or recess in theother.
